From b28e81e0889ff91cd3eb6c216f9d8cb11dd57c10 Mon Sep 17 00:00:00 2001
From: Mouse <mouse008@gmail.com>
Date: Fri, 23 Oct 2015 07:47:13 -0400
Subject: Fix minor output problem. Added MCEIES plaintext and decrypted
 output. Added output length where it was missing. Changed "Public key bits"
 output to Base64 to match cert.toString()
